SAN DIEGO San Diego authorities say a package explosion at a FedEx warehouse appears to have been sparked by batteries and was not intentional.
City fire spokesman Maurice Luque (Loo-kay) says two lithium batteries in a box made contact and exploded shortly after 6 a.m. Wednesday at the building in the Miramar neighborhood. No one was injured.
Police Lt. Dan Christman say employees who were sorting packages were about 6 feet away from the cardboard box when it exploded. They reported a flash and smell like gunpowder.
The building was evacuated. A police bomb squad was called in.
Police Detective Gary Hassen says they concluded the blast was an accident.
